  • Access to bytes array of a Bitmap

    - by Deulis
    1- In Windows CE, I have a Bitmap object in C#. 2- I have a C function in an extern dll that expects as parameters the pointer to a bytes array that represents an image in RGB565 format, width and height. This function will draw on this array of bytes. So I need to pass the byte array pointer of the Bitmap object, but I can find a practical way to get this pointer. One way is convert this Bitmap into a bytes array using a memory stream or something else, but it will create a new bytes array, so I will keep in memory both object, the Bitmap and the bytes array, but I don’t want it because the few available memory, that’s why I need to access to the bytes array of the bitmap object, not create a new bytes array. Anyone can help me?

    - by Cortopasta
    Trying to make a simple toggle menu, and I can't seem to hide/show the sub menu using this bit of jQuery: $(".topic news").mouseup(function(){ $(".feed groups").hide("fast", function(){ $(".feed messages").hide("fast"); $("ul.feed news").toggle("fast"); }); }); Here is the corresponding HTML: <div class="topic news"> <span>News Feed</span> </div> <ul class="feed news"> <li>News item #1</li> <li>News item #1</li> <li>News item #1</li> <li>News item #1</li> <li>News item #1</li> </ul> Any ideas?

  • SHFileOperation replace file dialog

    - by JHowzer
    Currently, SHFileOperation has some confirm file replacement dialog boxes that ask the user if they would like to replace a file or not. I find these useful, but I would like to be able to modify the scenario in which they occur. Instead, I would like to compare the file contents first with a bool compareFile() function I wrote. Then, if the files are identical the file replacement dialog box will not come up. Assuming, I already have a working compareFile() function, is there a way for me to do this? Thank you for your time.

  • functions in assembler

    - by stupid_idiot
    hi, i have philosophised about the purpose of stack a little bit and after some coding i figured out what is it's strength. The only thing that lies in my stomache is how does it work with functions? I tried to make some easy function for adding two numbers using universal registers but I suppose that's not how does it work in C for example.. where are all the parameters, local variables and where is the result stored? how would you rewrite this to assembler?(how would compiler for C rewrite it?) int function(int a, int &b, int *c){ return a*(b++)+(*c); } i know this example kinda sucks.. but this way i can understand all the possibilities

  • Ajax, not sending querystring data

    - by Tom Gullen
    var http = false; // Creates xmlhttp object if (navigator.appName == "Microsoft Internet Explorer") { http = new ActiveXObject("Microsoft.XMLHTTP"); } else { http = new XMLHttpRequest(); } http.onreadystatechange = function() { if (http.readyState == 4) { alert(http.responseText); } } // Functions to calculate optimum layout etc. function compute() { var statusSpan = document.getElementById("cwStatus"); document.getElementById("fader").style.display = ""; document.getElementById("computingWait").style.display = ""; statusSpan.innerHTML = "<b>Status:</b> Realigning sattelites" http.open("GET", "alg.aspx?cr=8&cc=7&sq=3,3", true); http.send(null); } This code sort of works, but the querystring data isn't being passed through. It keeps returning an ASPX error page which only happens when there is no querystring data. Thanks for any help

  • Converting a PHP array to class variables.

    - by animuson
    Simple question, how do I convert an associative array to variables in a class? I know there is casting to do an (object) $myarray or whatever it is, but that will create a new stdClass and doesn't help me much. Are there any easy one or two line methods to make each $key => $value pair in my array into a $key = $value variable for my class? I don't find it very logical to use a foreach loop for this, I'd be better off just converting it to a stdClass and storing that in a variable, wouldn't I? class MyClass { var $myvar; // I want variables like this, so they can be references as $this->myvar function __construct($myarray) { // a function to put my array into variables } }

  • Which event to catch for application shut down?

    - by xueru
    I am using jQueryMobile and phoneGap for a cross-device mobile application. I use html 5 local storage to persist records that worked on by user. I don't know which phoneGap event to catch just before application shut-down so I can make sure data is saved before shutdown completes. Base on suggestion from naughtur, I tried both unload and beforeunload events, neither of them got fired during app shutdown. Following is my code snip: function persistTasks(){ alert ("is unloading the app"); offlineTasklist.set("tasks", tasklist); } function init() { document.addEventListener("unload", persistTasks, false); login(); } $(document).ready(init);

  • overflow technique in stack

    - by metashockwave
    int main(void) { problem2(); } void doit2(void) { int overflowme[16]; //overflowme[37] =0; } void problem2(void) { int x = 42; doit2(); printf("x is %d\n", x); printf("the address of x is 0x%x\n", &x); } Would someone help me understand why overflowme[37] =0; from the doit2 function will overwrite the value of x? (please include Program Counter and Frame Pointer of the function doit2 in your explanation) Thank you! It works every time with Project properties-Configuration properties-C/C++ -Code Generation-Basic Runtime Checks set to "Default". so it's not an undefined behavior.

  • Any side effect of not using USES_CONVERSION

    - by Yan Cheng CHEOK
    Recently, I have a utilities function of // T2CA #include "ATLCONV.H" std::string Utils::CString2String(const CString& cString) { #if _MSC_VER > 1200 // Convert a TCHAR string to a LPCSTR // construct a std::string using the LPCSTR input CT2CA tmp(cString); std::string strStd (tmp); #else // Deprecated in VC2008. // construct a std::string using the LPCSTR input std::string strStd (T2CA (cString)); #endif return strStd; } I do several simple test it seems work fine. However, when I google around, I see most usage of T2CA in VC6, before they call, they will invoke USES_CONVERSION; Is there any thing I had missed out? Shall I invoke my function by : #else // Deprecated in VC2008. // construct a std::string using the LPCSTR input USES_CONVERSION; std::string strStd (T2CA (cString)); #endif

  • How to replace href using javascript regex in Firefox?

    - by Andrei
    I try to change some links on a webpage using the following code for jQuery on Rails $(function () { $('#lesson a').live('click', function () { $.getScript(this.href.replace(/^(http...[^\/]+)?\/+(.*)$/,'/ajax/\\$2')); return false; }); }) This trick works for Chrome and Safari, but fails (nothing happens on click) for Firefox and Opera. What can be wrong with the code? EDIT1: The webpage contains: <div id="lesson"> <a href="/subj1">Subject 1</a> ... </div> On click, a browser (i.e. Firefox and Opera) should make an ajax-request of /ajax/subj1.

  • How do I release an object allocated in a different AutoReleasePool ?

    - by ajcaruana
    Hi, I have a problem with the memory management in Objective-C. Say I have a method that allocates an object and stores the reference to this object as a member of the class. If I run through the same function a second time, I need to release this first object before creating a new one to replace it. Supposing that the first line of the function is: NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; This means that a different auto-release pool will be in place. The code to allocate the object is as follows: if (m_object != nil) [m_object release]; m_object = [[MyClass alloc] init]; [m_object retain]; The problem is that the program crashes when running the last line of the method: [pool release]; What am I doing wrong ? How can I fix this ? Regards Alan

  • What is the best regular expression for validating email addresses?

    - by acrosman
    Over the years I have slowly developed a regular expression that validates MOST email addresses correctly, assuming they don't use an IP address as the server part. Currently the expression is: ^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$ I use this in several PHP programs, and it works most of the time. However, from time to time I get contacted by someone that is having trouble with a site that uses it, and I end up having to make some adjustment (most recently I realized that I wasn't allowing 4-character TLDs). What's the best regular expression you have or have seen for validating emails? I've seen several solutions that use functions that use several shorter expressions, but I'd rather have one long complex expression in a simple function instead of several short expression in a more complex function.

  • Can I use a string variable to reference a class variable?

    - by rson
    Here's the scenario: I have an external swf file with x number of movieclips in its library that I load into a containing swf. Each MC in the external swf is linked with a class name and referenced on frame 1 as such var unique1:lineSequence1 = new lineSequence1(); the unique1 variable name will match a string variable I create in the containing swf: function initLines():void{ lineLoader = new Loader(); lineLoader.load(new URLRequest("theLines.swf")); //load external swf lineLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, linesLoaded); } function linesLoaded(e:Event):void{ var loadedswf:MovieClip = e.target.content as MovieClip; var initialLines = projects[0].pageid; //projects is an xmllist trace("initialLines: "+initialLines); //returns "initialLines: unique1" lines_holder_mc.addChild(loadedswf.[initialLines]); } I would like to use the initialLines variable as the reference to unique1 instead of hardcoding unique1 into loadedswf.unique1 to reference said variable in the loaded swf.

  • Capturing system command output as a string

    - by dreeves
    Perl and PHP do this with backticks. For example: $output = `ls`; This code returns a directory listing into the variable $output. A similar function, system("ls"), returns the operating system return code for the given command. I'm talking about a variant that returns whatever the command prints to stdout. (There are better ways to get the list of files in a directory; the example code is an example of this concept.) How do other languages do this? Is there a canonical name for this function? (I'm going with "backtick"; though maybe I could coin "syslurp".)

  • g++ doesn't think I'm passing a reference

    - by Ben Jones
    When I call a method that takes a reference, g++ complains that I'm not passing a reference. I thought that the caller didn't have to do anything different for PBR. Here's the offending code: //method definition void addVertexInfo(VertexInfo &vi){vertexInstances.push_back(vi);} //method call: sharedVertices[index]->addVertexInfo(VertexInfo(n1index, n2index)); And here's the error: GLUtils/GLMesh.cpp: In member function 'void GLMesh::addPoly(GLIndexedPoly&)': GLUtils/GLMesh.cpp:110: error: no matching function for call to 'SharedVertexInfo::addVertexInfo(VertexInfo)' GLUtils/GLMesh.h:93: note: candidates are: void SharedVertexInfo::addVertexInfo(VertexInfo&)

  • numpy arange with multiple intervals

    - by Heiko Westermann
    Hi, i have an numpy array which represents multiple x-intervals of a function: In [137]: x_foo Out[137]: array([211, 212, 213, 214, 215, 216, 217, 218, 940, 941, 942, 943, 944, 945, 946, 947, 948, 949, 950]) as you can see, in x_foo are two intervals: one from 211 to 218, and one from 940 to 950. these are intervals, which i want to interpolate with scipy. for this, i need to adjust the spacing, e.g "211.0 211.1 211.2 ..." which you would normaly do with: arange( x_foo[0], x_foo[-1], 0.1 ) in the case of multiple intervals, this is not possible. so heres my question: is there a numpy-thonic way to do this in array-style? or do i need to write a function which loops over the whole array and split if the difference is 1? thanks!

  • Jquery: encasing div and anchor link binded to same event.

    - by centr0
    im having trouble figuring out how to bind mouseout() to my entire nav bar including the links. when a user hovers over a link in #nav a sub menu is shown. all is well there. what i want to do is fadeOut that sub menu when the user hovers out of the entire #nav. my code for the mouseout: $('#nav').mouseout(function() { setTimeout(function() { //$('.sub-link').fadeOut(); }, 2000); }); when i hover over an anchor link which resides in #nav, i see the sub-menu. then i guess the mouseout() even fires and the sub-menu fades out. is there anyway to have the #nav and any anchor links within it to act as one? i'd paste my markup but even indenting it 4 spaces still shows as rendered html.. TIA

  • Regarding C typedef struct

    - by Bruce Duncan
    I have multiple instances of typedef struct box so box box1, box box2 etc. The members of the struct are length, width, height etc. typedef struct { int width; int height; } box; box box1; box box2; How can I create a function that operates on all the width members of each box instance? My confusion is how do I pass a pointer to a typedef struct member that works across all instances of box. I know how to pass a pointer to a specific instance member like box1.width but how to pass .width and then do box1.width=value; box2.width=value; box3.width=value; within the function?
